- 【Material & Durability】Crafted from high-strength brass with precision machining, these 3/8" OD x 3/8" NPT DOT Elbow Push fittings are built to withstand extreme pressure (up to 250 PSI) and resist corrosion, rust, and wear. The robust construction ensures long-term reliability in harsh environments, including heavy-duty trucking, trailers, and industrial pneumatic systems. Ideal for both commercial and off-road applications, these fittings meet SAE J1131 standards for superior performance.
- 【DOT-Approved Safety Compliance】Strictly certified by the DOT FMVSS 571.106, these fittings guarantee compliance with federal safety regulations for air brake systems. Each unit is rigorously tested for leak-proof performance, pressure resistance, and durability to ensure safe operation in commercial vehicles, buses, and trailers. DOT approval means you can trust these fittings for critical braking applications.
- 【Red Anti-Leakage Coating for Secure Sealing】The Air Brake Dot Fittings Feature a bright red permanent thread sealant coating that prevents air leaks and eliminates the need for additional Teflon tape or sealants. The high-visibility color makes inspection easy, while the chemical-resistant coating ensures a tight, vibration-proof connection even under constant pressure fluctuations.
- 【Tool-Free Design】Designed with user-friendly push-to-connect or quick-disconnect mechanisms, these dot fittings allow for effortless installation and removal without special tools. The smooth inner bore minimizes air flow restriction, while the ergonomic grip ensures a secure hand-tightened connection—saving time during maintenance or emergency repairs.
- 【Wide Industrial & Automotive Applications】Compatible with 3/8" air brake lines, suitable for semi-trucks, tractor-trailers, RVs, and industrial machinery. Use them for gladhands, brake chambers, relay valves, or air compressors. Weather-resistant and tested for -40° F to +200° F（-40°C to +93°C）operation.
